Off-grid kits include solar panels, off-grid solar inverters, charge controllers, solar storage batteries, enclosures and mounting. Browse our selection of pole mounted kits, continuous power ready kits, generators, solar appliance kits, and solar ready battery systems. There are also hybrid on-grid / off-grid systems with batteries that deliver grid-tied savings and backup power in the event of grid outages.
Benefits of Off-Grid Solar Kit
Reliable Power Independence
Off-grid solar kits free you from utility companies, power outages, and escalating electricity rates. The system generates consistent, renewable power regardless of grid failures or remote location challenges. This is invaluable for rural properties, emergency preparedness, and anyone prioritizing self-sufficiency.
Access to Energy 24/7
Solar batteries store excess energy produced during the day, ensuring continuous power after sunset. Modern battery systems offer 10+ year lifespans with minimal maintenance, providing dependable energy reserves during extended cloudy periods or peak demand times.
Scalable & Customizable Systems
You can start with a basic off-grid solar kit for cabin essentials, and then expand as needs grow. Add panels to increase generation capacity, stack batteries for extended storage, or upgrade inverters for larger loads-your system evolves with your lifestyle.
Easy Installation & Integration
Today's off-grid solar kits feature simplified designs with clearly labeled components and comprehensive instructions. Pre-wired systems and plug-and-play connections minimize installation complexity, while mounting systems adapt to various roof types and ground installations.
Remote Locations: Off-grid solar kits are widely used in remote areas where utility power is unavailable or unreliable. This includes remote cabins, cottages, or vacation homes located far from the grid. Off-grid solar systems provide a reliable and independent source of electricity for lighting, appliances, and other power needs.
Off-Grid Homes: In some regions, it can be costly or challenging to connect a home to the electrical grid. Off-grid solar kits are a popular choice for homeowners who prefer to generate their own electricity. These systems power the entire household, including lights, appliances, pumps, and other electrical devices.
RVs and Boats: Off-grid solar kits are commonly used in recreational vehicles (RVs) and boats. They provide a convenient and eco-friendly way to power lights, refrigerators, entertainment systems, and charge electronic devices while on the move.

How to Choose the Right Off-Grid Solar Kit
System Capacity & Energy Demand
Calculate your daily energy consumption by listing all appliances and their operating hours. A 3kW system suits basic cabin needs, while full homes typically require 6-12kW systems. For instance, our SunGold off-grid solar kit handles substantial loads. It's important to match solar panel output to your consumption patterns, accounting for seasonal variations and peak usage times.
Battery Type & Storage Capacity
Lithium-ion batteries dominate modern off-grid systems, offering 5,000+ cycles and 80% depth of discharge. Size your battery bank for 2-3 days of autonomy during cloudy weather. Also, you have to consider temperature ratings for extreme climates and expansion capabilities for future needs.
Inverter Compatibility
Choose inverters that match your maximum simultaneous load requirements. Verify the inverter's voltage output aligns with your system needs and that its surge capacity can handle motor startup demands, typically 2-3 times the running wattage. Modern hybrid inverters, for instance, offer additional flexibility by supporting multiple operating modes and future system expansion.
Scalability & Upgrade Potential
Invest in expandable systems accommodating future growth. Modular designs allow adding panels, batteries, and inverters without replacing existing equipment. Choose charge controllers and inverters with excess capacity for seamless expansion. Stackable battery systems and parallel-capable inverters ensure your off-grid solar setup grows with changing energy needs.
Installation and Maintenance
DIY vs. Professional Installation
Your off-grid solar kit installation can be done by a professional, or you can DIY. Small, simple systems, particularly portable ones, can often be done yourself. However, if you have a large system, a ground-mounted system, or complex shading on your roof that requires technical expertise, it's best to hire a professional.
5 Regular Maintenance Tips
Routine cleaning 1-2 times per year to remove dirt, dust, and bird droppings.
Conduct visual inspections of panels to look for cracks, scratches, or chips.
Regularly monitor your battery's state of charge to ensure it's not over- or under-charging.
Inspect battery terminals and inverter connections for loose or damaged wires or signs of corrosion.
Keep the inverter clean of dust and debris, and always ensure good ventilation.
